    If I could give this 12 stars I would. This is hands down the best skincare product I have ever used. I feel beautiful without makeup, something I’ve never felt. Thank you Dr. Kay!

    Love. Love. Love. I don’t know what I did before this product. My skin stayed hydrated especially during the winter season.
